BACKGROUND: Nitrogen is a basic plant component, playing a decisive role in the intensification of plant production. Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. OBJECTIVES:</s...

In order to evaluate genetic diversity of grain yield, nitrogen uptake efficiency and selecting superior varieties, a factorial experiment with the based on Complete Blocks design with four replications was carried out in Saatlo agricultural research station, six corn genotypes (single cross 301,370,540,700,701 and Back cross) and three amounts of nitrogen fertilizer (urea) (27 as a control, 11...

abstract in order to evaluate the effects of different depths of irrigation by sprinkler irrigation system on water use efficiency (wue) of new early maize cultivar ksc302, an experiments was carried out in karj during 2006 and 2007. experimental design was split plot based on randomized complete blocks with three replications. main plots were three irrigation levels: 75%, 100% and 125% etc (es...

Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers i...

The high error rates of viral RNA-dependent RNA polymerases create heterogeneous viral populations whose disparate RNA genomes affect each other’s survival. We systematically screened the poliovirus genome and identified four sets of dominant mutations. Mutated alleles in capsidand polymerase-coding regions resulted in dominant negative phenotypes, probably due to the proteins’ oligomeric prope...

Amyloid A plaques are a key pathologic feature of Alzheimer disease (AD), but whether plaque sizes increase or stabilize over the course of AD is unknown. We measured the size distribution of total immunoreactive (10D5-positive) and dense-core (Thioflavin SYpositive) plaques in the temporal neocortex of a large group of subjects with AD and age-matched plaque-bearing subjects without dementia t...

Viral hepatitis is one of the most important liver diseases in the world. Duration of hepatitis C virus (HCV) infection and response to standard therapy is strongly related to HCV genotypes. Geographical distribution of HCV genotypes is also important for epidemiological studies. We aimed to determine the distribution of HCV genotypes and their prevalence in Eastern Turkey. Fifty eight Anti-HCV...
